I need some advice on nutrient feeding in an ebb and flow hydroponic system. At what point is my plants strong enough to feed on the mild growth stage on the nutrient feeding schedule (include plant height,age,etc.). I am starting my plants on a 400 watt metal halide tomorrow, they are in 2-20 watt fluorotubes and they are almost 2 and a half weeks old from seed. 3 of them have excellent growth but one of them is still quite small. Please help out if you use and are familiar with General Hydroponic Flora Series Hydroponic Nutrients. Any help is appreciated - Thank You.
